Electric Cars In Developing Nations Could Do More Harm Than Good

While electric cars seem to provide a host of environmental benefits, the reality is that their use in some countries could actually increase greenhouse gas emissions

As Tesla gets set to roll out the remarkably affordable Model 3 for the global market, and self-driving cars have come closer and closer to becoming a reality, the paradigm shift towards electric cars is becoming a global phenomenon. Long-standing automakers, such as Volvo, are beginning to wean their product lines off of fossil fuels in favour of electricity. The environmental benefits of emissions-free electric vehicles have made this transition inevitable. But are they universal?

The most obvious benefit of electric cars is that they don’t burn fossil fuels. This obviously eliminates tailpipe emissions, but it also eliminates the huge amounts of greenhouse gases produced during the extraction, transportation, and refining of crude oil into petrol or diesel. The mining of lithium for EV batteries can also be a dirty process, but the net environmental impact can offset that of petroleum-propelled vehicles over the vehicle’s lifespan.

There is one caveat that must be applied, however. The energy required to charge the batteries has to come from somewhere, too. While wind and solar energy are advancing at a historical pace, they currently account for a fraction of the world’s energy production. What’s more, the power grids of some of the world’s most populated countries depend on some of the dirtiest methods of electricity generation.

The world’s two largest countries, China and India, depend mostly on coal-fired power plants to provide electricity to over two billion people. These plants are very dirty, producing flue gases that are major contributors to anthropogenic climate change. Hydroelectricity is a major source of renewable electricity, but hydro projects can have serious negative effects on their surrounding environment. This ultimately leaves solar energy and wind energy as the two sources of energy that give EVs the best chance of mitigating environmental damage.

In order for wind and solar to satisfy the demand for clean electricity, however, many of the world’s countries will have to make some serious upgrades to their national power grids. This would require monumental investments in infrastructure; especially in countries such as India, where the power grid is barely sufficient as it is.

It would be one issue if all that was needed was to replace the existing electrical system. But that’s just a start. If EVs are truly going to be driven by the population at large, the demand for electricity is going to increase by a massive amount. This could mean that these countries might have to keep the dirty plants running to keep up with the system load. In fact, a reasonable scenario is that these countries would have to increase their reliance on coal and gas-fired power plants just to accommodate the transportation network.

This isn’t to suggest that we shouldn’t be driving electric cars. In Norway, 98% of all electricity is produced by renewable sources (hydro, wind, solar, etc.). This means that replacing the internal combustion engine with electric engines could reduce Norway’s greenhouse gas emissions significantly. To me, that sounds like a good idea.

But if you’re really concerned about saving the planet, you’ve got to consider the logistics of the area’s power system before you can say whether or not EVs will actually provide benefits. Despite the best of intentions, lawmakers and environmentalists must come to terms with the fact that EVs are not going to be the be-all, end-all solution to automotive emissions.

Clarkson’s already said that when he tested Nissan Leaf and peugeuot whatever.. forgot the name. That’s why i’m stick with my internal combustion engine. Or when they finally mass produce hydrogen fuel cell.

screw electric cars well we could stil go for hybrids (not the prius) at least they can be a bit of fun why wont we focus more on mazda’s skyactive might not be much but it could probably help

A recent swedish study showed that the way most batteries for electric cars are made now actually produce so much CO2 that you can run a Volvo V70 D2 for 200k km before the electric car is greener. And that’s excluding the production CO2 for both cars. So if you get an electric car you need to make sure the battery is green.
